Contact Working Opposite Way

[MJE]

Hello All

 

quick question that I cant find anywhere

 

can someone confirm that door contacts are supposed to be "closed" when the magnet is attached

 

I have a galaxy intruder panel i'm installing and everything is set up apart from the door contact as its working in the opposite way i want it to

 

it is saying door open when closed and only sets if the door is open

 

it has the supplied EOL resistor across it  (1K) and is set to 1k in the panel

 

I cant find any option to change it in the panel, i know it will be so something so obvious just wanted to make sure before i buy another contact

 

 

 

thanks

You probably havnt seen the problem correctly , what's the full log say when your setting

Are using an exit time?

The eBay description is "normally closed"

To my way of thinking that means the contact is closed without any outside influence (eg magnet).

When the magnet is adjacent to the contact, the contact will open.

Meant for door alarms i reckon.

You can get them normally open. Have you metered it?

Yes, Knights do certain ones as NO

Yep use them a lot on nurse call systems for door monitoring.

Is that a single resistor?  It should have 2 fitted typically if each sensor is on its own circuit.(1 inline with the door reedswitch and another across the reed switch)  If you have installed only the 1 resistor 'across' it then with the door open it would show tamper and stop you arming, but with the door open it would show healthy and allow you to set.  Just a thought.
